Didn't work properly form me Filament get stucked

Any tips on how to load it for smooth feeding? Also do you glue any of the parts?

Looks very nice! Going to try it on my https://www.printerpen.nl/3dpennen!

Maybe someone can design a holder for the 3d printing pen as well!


Thanks for this great design. The clip sits a little loose on the pen, had to tape it to make it stay. But it seems that the spool does not rotate as it should, instead the filament pulls from the wrong side and breaks if i forget to rotate the spool manually:

Ok, fixed the issue by adding a plastic cover from a connector i had around. Works great now :)




Monoprice had some 3d Pens for $15 shipped.

Awesome. Just got a 3d pen for a project I'm doing and also thought the filament hanging was weird. What model pen do you have?

I don't think it really has a name, but eBay and Amazon are full of them.

Haha yeah they are all over the place. I only ask to help me and others figure out if the attachment is the same. Maybe you have the demensions of the pen so we can compare to ours?

Also on the off chance you don't know your thing is featured on hackaday.com

Well, the top of my pen measures 30x46mm. I'm guessing these pens all came from the same injection mold, so there shouldn't be an issue.
